The Empress’ two hundred and fifty-first birthday is just a few days away, yet there is little cause for celebration as Rarity’s Empire is crumbling before her eyes. Bad luck somehow meets her at every turn, and there’s a grim shadow looming over any hope for her nation and her crystal ponies. With a powerful darkness locked within her own mind, will the voices in her nightmares tear her apart? Or can she learn to rely on those she once called friends before it's too late?

This story was designed with new and old readers in mind. I have made sure to carefully place information to touch on the important facts to remind those that had read the first book of what happened, and to let new readers know what is going on in this one. Not everything is going to be explained from the last book at once, but it will be eventually covered.

So it is not necessarily a requirement to read Empress Rarity’s 250th Birthday, but it is highly recommended.

"The pieces are set, and the dice are in play. But does every pony have the heart for this day?"

Nearly two hundred years have passed since Rarity Belle merged with the Crystal Heart and took the throne of the Crystal Empire. Since then, through her care, determination, and vision, the Empire has flourished like never before. Now Empress Rarity stands as not a ruler of a providence, but the monarch of a rising superpower.

Today though, is the Empress' Birthday, and Lady Merry Sapphire, seneschal to the Empress, is determined to make this the best birthday Rarity has ever had. Little does she know that not everypony shares her enthusiasm for today...

Notes:This is an official prequel to the Princess Twilight Sparkle's Birthday stories, created by Autumnschild. This story will develop and expand much of the world we made, but taking place 250 years before PTS500 and its sequel, PTS505. Due to its time gap and status as a prequel, you do not need to read the stories created by Autumnschild, and I have done my best to help that. However, knowing what happened in them will help you be a bit more aware of what is going on, and I encourage you to go read them for they are very enjoyable.
